Stan,

It can be made to work, but will be a real "bear" to adjust to resonance 
unless you separate the ends.

If you are feeding with 300 ohm twinlead, why not make a 66 foot long 
center fed dipole out of it.

Alternately if this is for portable work, us no feedline at all - just a 
BNC to binding post adapter at the KX1. Use 2 lengths of wire as is 
shown on page 10 of the KXAT1 manual.
